Vista screen refreshes every few seconds

[Guest]

Vista refreshes the screen every few seconds (it blinks ever so briefly) and
any keys pressed (such as shift) or menus open are cancelled. This means it
is difficult to access long menus and impossible to use certain selection
tools in Photoshop etc. I suspect it's a rogue driver. Anyone else had these
symptoms?

I have the same experience on my Toshiba Lap top. I think that it may be
causing blackouts on cds and dvds that I burn. I cannot relate the screen
blanking to any particular activity.

Thanks,
It's not been happening for a wee while now. I think I eventually tracked it
down to a driver update, possibly an ethernet controller update, but might
have been an NVidia video driver. It's difficult to be 100% as these things
are never totally consistent.
